New Scientist magazine reported in June that five meters of future sea-level rise is already locked in, due to the steady collapse of the West Antarctic Ice-Sheet. If we don’t act rapidly, their staff reported, it will be twenty metres.

The full extent of the flooding will not happen for several thousand years, but “locked-in” is the phrase they used.[1] Venice, New York, Miami, San Francisco, Vancouver, London, Mumbai, Kolkata; large parts of Holland; a large part of Bangladesh and many cities in China—all will be under water.[2]
